I have an old dell e6520 laptop (2013) with the above integrated card.
linux kernel: 6.2.15-300.fc38.x86_64
xorg-x11-drv-nouveau.x86_64 1:1.0.17-5.fc38
>>>> xrandr -v
xrandr program version 1.5.2
Server reports RandR version 1.6>>> xrandr -q
LVDS-2 connected primary 1920x1080+0+0 (normal left inverted right x axis y
axis) 344mm x 194mm
1920x1080 60.04*+ 60.01 59.97 59.96 40.02 59.93
...
HDMI-1-1 connected 1680x1050+1920+0 (normal left inverted right x axis y
axis) 608mm x 345mm
1920x1080 60.01 59.97 59.96 60.00 50.00 59.94
59.93 30.00 24.00 29.97 23.98
1680x1050 59.95* 59.88
For some reason I am unable to set 1920x1080 for the HDMI.
The HDMI cable leaves the laptop and goes in the HDMI input of a Samsung
U28E570 4u UHD screen.
I have a large amount of nouveau related output in kernel messages,
starting with this call trace:

and more in attached file
1. Can I reach a higher resolution on the Samsung screen?
2. Displaying appears slower (it feels like more CPU is used). Is there a
misconfig somewhere?
